The GF had a failure of that bolt on her first trip out.Granted, she may have had no idea one her first solo run what she did wrong but it broke. They are DESIGNED to break to prevent costly damage!I bought 20 spares through my dealer and we split them in half. Spares are carried on-board at all times. I broke one docking. I missed the bungee and was going too darn fast. 1min fix and back out
